I just upgraded my aspose java products to latest version (21.8).
After the upgrade a pptx with animation doesnt get converted (blank page).
When I used version 19.2 it did get generate well.
Adding how it was generated in 19.2 + how it generate in 21.8 (aspsoe-slides).
After a small research I noticed that it stop working well between version 20.10 to 20.11 of aspose slides.
I coudnt upload the source file because its too big. (Only animation inside the pptx)
I uploaded the two outcomes of the pdf.
